The GLOBALfiber GF-4G-LGX01A-GX5-4 is a passive 4 x 5CH CEx WDM coexistence multiplexer for GPON / XGS-PON / 25/50G-PON / RF Video / OTDR. It combines and separates the supported wavelength bands on shared fiber infrastructure, helping operators add services without replacing the existing access fiber.
This LGX4 plug-in module version is intended for FTTH, FTTB and service-provider access networks. Select it by the required service groups and optical connector types; each service must use optics within its assigned passband.
